Thank you for the reply. Just before I left home this afternoon, I checked the History Log and saw MN DNR Forestry Cambridge logged and time stamped. It was the usual frequency and PL tone (analog). I will have to watch for APCO P25 modulation on those.
One of the other things I seem to recall is that they often work with federal partners, in addition to local partners. Their federal partners are likely on convention VHF. Having the ability to use only one band, namely VHF high band, makes a lot of sense. I recall seeing a channel plan in one of their vehicles a while back and it had a large number of frequencies for MN DNR and a number of federal VHF channels, including USFS, BIA, NPS, etc.
